There's supposed to be a Showcase edition of the 70's "Shazam" run released this December or so, IIRC.
** Gasp! Sputter! **
What about Monster Society of Evil!?!?
Guess that's what the DC Archives series is for; the Showcase volumes seem dedicated to reprinting Silver and Bronze Age era stories, thus the "Shazam" series of the 70s getting reprinted (and presumably just the stories originally written for it, not any of the reprints of Golden Age material included...).
